Definitions

  • the invention relates to a pipe clamp according to the preamble of claim 1.
  • Such a pipe clamp known from DE-GM 19 45 024 consists of a one-piece clamp ring, at the facing ends of which flanges are bent outwards.
  • a bore is formed in one of the flanges, through which a locking screw is passed, the head of which bears on the outside of the flange.
  • a receiving hole with a thread for the locking screw is formed in the opposite flange.
  • a fastening device is provided, by means of which the pipe clamp can be fastened to a ceiling, wall or other supporting structure.
  • the clamp ring can be used with a Inner sleeve made of rubber or the like.
  • a pipe clamp which also has an integral clamp ring.
  • a snap lock is formed on the mutually facing ends of the clamp ring. This consists of a locking lug formed at one end of the clamp ring and a locking lug receptacle formed in the area of the other end of the clamp ring.
  • aligning a tube received in the clamp ring is very tedious when the clamp ring is already closed. Alignment is not possible with the clamp ring open.
  • the invention has for its object to design a pipe clamp of the generic type so that a simple alignment of inserted in the pipe clamp pipes is possible with the clamp ring not yet tightened.
  • a locking bracket is attached to one end of the clamp ring, which is pivoted for provisional closing of the clamp over a web formed at the other end of the clamp ring.
  • This striker therefore forms an assembly aid. After inserting a pipe into a pipe clamp that is usually already attached to a ceiling, wall or other supporting structure, this locking bracket can be closed with only one hand, so that the pipe is temporarily held in the clamp ring. It is ensured by the measures according to claim 2 that the pipe received in the clamp ring still has enough air so that it can be aligned.
  • a flange is used as a web according to claim 3, which carries the receiving hole anyway. No additional configuration of the pipe clamp is necessary on this side anyway.
  • the further embodiment according to claim 4 also ensures that no additional measures are required for fastening the striker to the clamp ring. It is ensured by the development according to claims 5 and 6 without additional measures on the clamp ring that the striker is captively pivotally mounted in a defined position on the flange and can thus be pressed over the web with only one hand when closing.
  • the training according to claim 7 makes it possible Bending the locking bracket from a wire, which at the same time ensures that the locking bracket can be removed from the pipe clamp in a simple manner if it should no longer be desired there after the pipe clamp has finally been closed.
  • the further development according to claim 8 ensures that the division of the crossbar does not result in the striker being able to open.
  • the striker according to the invention is very preferably applicable to pipe clamps with an inner sleeve made of elastic material, since these already hold a pipe relatively firmly, even if they have not yet been finally clamped together.
  • the striker according to the invention can basically be used with one-piece or two-piece clamp rings, but it can preferably be used with one-piece clamp rings.
  • the development according to claim 12 ensures that when the striker is closed, the closing screw with its tip can be attached to the receiving hole without the flange and web having to be pressed together beforehand by hand.
  • the locking screw can therefore already engage in the receiving hole when the locking bracket is closed.
  • the pipe clamp shown in the drawing has a one-piece clamp ring 1, which is bent from a sheet metal strip. It is provided essentially over its circumference with stiffening ribs 2 pushed outwards. At one end, a flange serving as a web 3 is approximately radially behind turned outside. In its other end, a flange 4 which is approximately the same as the web 3 in the outer contour is also bent approximately radially outwards. In the longitudinal center of the clamp ring 1, i.e.
  • a fastening device 7 in the form of a nut is fastened by welding on the outside of the clamp ring 1.
  • the pipe clamp can be attached to a corresponding threaded bolt on a ceiling, wall or other supporting structure. This part of the clamp ring 1 is thus fixed in place with such an attachment.
  • the inside of the clamp ring 1 is lined with an inner sleeve 8 made of rubber or the like, which surrounds the two side edges of the clamp ring 1 with fastening flanges 9.
  • This inner sleeve 8 lines the clamp ring 1 over its entire circumference; for reasons of graphic clarity, only a short section is shown.
  • a bore 10 is formed in the flange 4, through one of the locking screws 11, designed as a self-tapping screw, is held against loss in the flange 4 by an elastic locking washer 12 so that its screw head 13 lying against the flange 4 is always at least close to the flange 4 and also, when the clamp ring 1 is still open.
  • the hole 10 and the locking screw 11 are assigned a receiving hole 14 in the web 4, into which the locking screw 11 can be screwed while cutting a thread.
  • the receiving hole 14 is formed in a funnel shape towards the outside, that is to say away from the flange 4, as a result of which the web 3 in the edge region of the receiving hole 14 is deformed outward from the flange 4 into a projection 15.
  • a striker 16 is articulated to the flange 4, which is roughly rectangular, as can be seen in FIG. 2, as a rough approximation. It consists of a sufficiently stiff wire.
  • a crosspiece 17 of the striker 16 is arranged between the screw head 13 and the clamp ring 1 in the corner region between the clamp ring 1 and the flange 4 and forms the pivot axis of the striker 16.
  • the two legs 18, 19 of the striker, which run approximately at right angles to the crosspiece 17, are immediate Behind the side of the flange 4 facing the web 3, it is provided with an indentation 20 forming a projection, the clear distance between which is smaller than the width of the flange 4.
  • the striker is therefore not only in the plane of the flange 4, but also perpendicular to it, captively attached to the flange 4, the clearance of the indentations 20 relative to the flange 4 being so great that the pivoting movement of the striker 16 around the crosspiece 17 is not hindered.
  • the crossbar 21 opposite the crossbar 17 is formed by the inwardly bent ends of the wire. This crosspiece 21 is therefore divided. It runs parallel to the crosspiece 17.
  • the striker 16 is somewhat shorter than the locking screw 11, i.e. when the locking bracket 16 is pushed over the web 3, its tip protrudes into the receiving hole 14. The tip of the locking screw 11 comes into contact with the receiving hole 14.
  • the screw head 13 lifts off from the flange 4, which allows the locking washer 12 without further ado.
  • the clamp ring 1 is temporarily closed, the transverse web 21 lies against the web 3 between the projection 15 and the clamp ring 1. To this extent, it is also protected against unintentional loosening of the connection between the flange 4 and the web 3 produced by the striker 16.
  • the crossbar 21 forms with the projection 15 a kind of locking connection.
  • the web 3 and the flange 4 are somewhat narrower than the clamp ring 1, so that the striker 16 does not protrude laterally beyond the clamp ring 1.
  • the closing screw 11 is pressed in the direction of the web 3 and screwed into the receiving hole 14, the flange 4 and web 3 are moved towards one another, whereby the clamp ring 1 is closed.
  • the crosspiece 21 of the striker 16 is released from the web 3 and loses its function.
  • the legs 18, 19, which run obliquely due to the indentations 20, slide over the side edges of the web 3 and are thus spread apart. After the clamp has been closed completely, the striker 16 is spread so far that it can be removed from the web 3 and the flange 4 without additional tools.
